Patented (let. 2, 19233.

To; all whom it may coflmm:

Be it lmown that T. JAMES a citizen of the United- States, residing atCamden, in the county offlamdenand State of New Jersey, have invented anew and useful Wrench, of which the. following is a specification.

The device forming the subject matter of this invention is adapted togrip internally, nipples and the like to the end that the nipples orother objects may be threaded out of any part with which they areassembled.

The invention aims to provide novel means for operating and controllingand mounting the element which immediately grips the nipple or otherobject to be held.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanying drawings t Figure 1 shows in side elevation, adevice constructed in accordance withthe invention; Figure 2 is alongitudinal section wherein parts appear in elevation; Figure 3 is across section on the line 33 of Figure 2; Figure 4 is a cross section onthe line t tt of Figure 2.

In carrying out the invention there is provided an elongated body 1equipped at one end with flat surfaces 2 adapted to receive a wrench orthe like, the body 1 being provided, at said end. with flat surfaceswhich are longer than the flat surfaces 2., the surfaces 3 beingdisposed at right angles to the surfaces 2, and being adapted to bereceived in a vise, or the like. to the end that the tool may be heldfixedly, should it be desired to hold the tool, rather than to rotateit. The body 1 has a trough-shaped extension 4 provided with inclinededges 5. A bore 6 is formed in I RENCH.

The grip has alongitudinal rib 10 received slidably in that portion of the bore 6which is located in the extension 1. The rib 10 is provided with aninternal slot 11 receiving the flattened end 31 of a connection 12,preferably in the form of a rod, the connection 12 being located in thebore 6. is mounted in the rib 10 and extends transversely of the slot11, the flattened end 81 of the connecting rod 12 being mounted on thepivot element 14.

The numeral 15 marks a'nut having a refducedneck 16 carrying a sphericalhead 1 ternal ridges 50, enhancing the hold of a tool on the nut,although, if desired, the nut may be manipulated by hand. a bore 18,into which one end of the rod 12 is threaded, as shown at 19. Cap pieces20 are attached by securing elements-21 to the end of the body 1 and aresupplied with seats 22 complemental to the seat 7 in the body 1, thespherical head 17 of the nut 1.5 being mounted to rock in the seats 7and 22. s t

In practical operation, when the nut 15 is rotated, the connection rod12 will be moved longitudinally, and the grip 8 will be movedlongitudinally, the grip 8 also moving transversely, because the gripslides on the inclined edges 5 of the troughshaped The nut 15 may beprovided with eX-' The nut 15 has a 1 pecan A pivot element 14: I

lVhat is claimed is 1. A device of the class described comprising a bodyhaving an inclined edge; a grip mounted to slide on said edge; a nutmounted to rock on the body; a connection threaded into the nut; andmeans for uniting the connection with the grip.

2. In a device of the class described, a body having an extensionprovided with an inclined edge, the body being supplied with a boreprolonged into the extension; a grip mounted to slide on said edge ofthe extension and including a rib extended into that portion of the borewhich is located in the extension; a rod located in the bore andpivotally connected with the rib; a nut including "a spherical headmounted to rock on the body; and a rod, one end of the rod beingpivotally connected with the grip, the other end of the rod beingthreaded into the nut, the rod being located in the bore.

In testimony that I claim the foregoing as my own, I'have heretoaflixed, my signature in the presence of two Witnesses.
